This is literally a ristricted shot. You should also grind a bit finer than normal espresso so you still end up with a 30 second shot, but about 2/3rds to half the total brew volume that you get with normal espresso.
But does it have to? The basics: a traditional espresso shot usually involves approximately 18 to 20 grams of espresso, with water extracted through it at high pressure to yield around 30 grams of liquid. Your local fancy-pants shop may well draw you a shorter shot, i.e. one with even less volume.
